      There are no clear steps to reproduce, but the general idea was

      • to setup the architecture as described in the doc linked in description
      • Create several kie-server instances using s2i build. Using s2i template parameters we made the kie-servers to connect to smart router
      • Go to Execution servers and try to perform some admin operations with the containers (start / stop / remove).

      In our "smart router + monitoring workbench" test day setup described here we saw several NullPointerExceptions in the server console of smart router after some basic manipulations in ServerManagement ui:

      The NPE is apparently coming from here.
